Another option is detective stories like Sherlock Holmes. These stories revolve around solving mysteries, using logic and deduction.

Fairy tales can be great alternatives. Take 'Cinderella' for instance. It's a story about kindness, hope, and the triumph of good over evil. The story follows Cinderella's journey from being mistreated to finding her true love and happiness through her good nature.
